Children’s services were against this info being released according to the report, it was because the Press applied to the judge after being granted more access to the Family Court:
“The reporting of the sibling link was not supported by the local authority and England's Children and Family Court Advisory and Support Service (Cafcass), which advises courts about children's best interests.
The Met Police said it was up to the court to determine whether the link between the children should be reported, but they told the court they did not wish to “inadvertently promote or encourage struggling mothers to abandon unwanted babies in public spaces””
“East London Family Court is taking part in a transparency pilot, which has been extended to cover almost half the family courts in England and Wales. This makes it easier for the BBC and other journalists to report cases.”
”The BBC and PA Media argued in court that it was a matter of public interest that the three children had been abandoned at birth by the same parents.”
